CompTIA DataX (CNX-001) — Question 74

An administrator must ensure that credit card numbers are not contained in any outside messaging or file transfers from the organization. Which of the following controls meets this requirement?

Answer options

• A. Intrusion detection system
• B. Egress filtering
• C. Data loss prevention
• D. Encryption in transit

Correct answer: C

Explanation

The correct answer is C, Data loss prevention, as it specifically focuses on preventing sensitive data, like credit card numbers, from leaving the organization. Options A and B do not directly address the prevention of sensitive data leaks, while D, although important for securing data during transfer, does not prevent the information itself from being sent.
